Training

The crew was completing a training flight from Kuala Lumpur-Subang Airport when on final approach to Butterworth Airbase, the twin engine aircraft went out of control and crashed, coming to rest against the perimeter fence. The aircraft was partially destroyed by impact forces and one crew member was killed while three other occupants were injured. Weather conditions were considered as good at the time of the accident.

A Beech 200 Super King Air aircraft operated by Air Nunavut as flight 200, was on a training flight at Iqaluit, NU (CYFB) to upgrade a candidate to captain status. A VFR circuit was executed to simulate a flapless landing. While in the circuit, the crew experienced an actual communication failure on COM 1 while two other aircraft were inbound to Iqaluit. At the end of the downwind leg, a flap failure was simulated and the crew carried out the appropriate checklist. However, the landing checklist was not completed and the aircraft landed with the landing gear in the up position on runway 16. The aircraft skidded on the belly and came to a stop on the runway between taxiway A and G. The crew declared an emergency and evacuated the airplane with no injuries. The aircraft sustained damage to the belly pod and both propellers.

The crew was completing a local training exercise at Montijo AFB, consisting of touch-and-go maneuvers. During the takeoff roll on runway 26, the four engine aircraft deviated from the centerline to the left then went out of control, veered off runway to the right and eventually crashed 1,460 meters past the runway threshold, bursting into flames. Four crew members were injured while three others were killed. The aircraft was destroyed by a post crash fire.

According to the pilot in command (PIC), he was conducting an instructional flight for his "new SIC (second in command)," who was seated in the left seat. He reported that they had flown two previous legs in the retractable landing gear-equipped airplane. He recalled that, during the approach, they discussed the events of their previous flights and had complied with the airport control tower's request to "keep our speed up." During the approach, he called for full flaps and retarded the throttle to flight idle. The PIC asserted that there was no indication that the landing gear was not extended because he did not hear a landing gear warning horn; however, he was wearing a noise-cancelling headset. He added that the landing gear position lights were not visible because the SIC's knee obstructed his view of the lights. He recalled that, following the flare, he heard the propellers hit the runway and that he made the decision not to go around because of unknown damage sustained to the propellers. The airplane touched down and slid to a stop on the runway. The airplane sustained substantial damage to the fuselage bulkheads, longerons, and stringers. The SIC reported that the flight was a training flight in visual flight rules conditions. He noted that the airspace was busy and that, during the approach, he applied full flaps, but they failed to extend the landing gear. He added that he did not hear the landing gear warning horn; however, he was wearing a noise-cancelling headset. The Federal Aviation Administration Aviation Safety Inspector that examined the wreckage reported that, during recovery, the pilot extended the nose landing gear via the normal extension process. However, due to significant damage to the main landing gear (MLG) doors, the MLG was unable to be extended hydraulically or manually. He added that an operational check of the landing gear warning horn was not accomplished because the wreckage was unsafe to enter after it was removed from the runway. The landing gear warning horn was presented by an aural tone in the cockpit and was not configured to be heard through the pilots' noise-cancelling headsets. When asked, the PIC and the SIC both stated that they could not remember who read the airplane flight manual Before Landing checklist.

The commercial pilot was entering the airport traffic pattern for landing during a familiarization flight. He reported that he turned on the carburetor heat, switched the fuel tank selector to the right fuel tank, and shortly thereafter, the engine experienced a total loss of power. The pilot attempted numerous times to restart the engine but was unsuccessful. After realizing that he would not be able to reach the runway, he decided to make a forced landing to a small field. During the landing approach, the airplane contacted a power line, nosed over, and came to rest inverted, resulting in substantial damage to the wings and fuselage. During the postaccident examination of the airplane, about 16 ounces of water were removed from the fuel system. Water was present in the lower gascolator, the fine fuel filter (upper gascolator), and subsequent fuel line to the carburetor inlet. A brass screen at the carburetor inlet and 2 carburetor fuel bowl thumb screens also contained corrosion, water, and rust. The approved aircraft inspection checklist called for washing the carburetor and main fuel filter every 50 hours and cleaning and/or replacing the fine fuel filter every 100 hours. The fine fuel filter is not easily accessible and not able to be drained during a preflight inspection. The mechanic who completed the most recent inspection stated that he did not drain or check the fine fuel filter. The last logbook entry that specifically stated the fuel filters were cleaned was about 4 years before the accident.

The crew (one pilot under supervision and one instructor) departed Girona-Costa Brava on a local training flight. Following two successful landings and touch-and-go manoeuvres, the crew initiated a new approach to complete a full stop landing. The aircraft belly landed and slid for few dozen metres before coming to rest on the runway. Both pilots evacuated safely and the aircraft was damaged beyond repair.

The private pilot, who was the owner of the airplane, and a flight instructor were performing a recurrent training flight. Radar data showed that the airplane departed and climbed to an altitude about 5,000 ft above ground level. About 5 minutes after takeoff, the airplane conducted a left 360° turn followed by a right 360° turn, then continued in level flight for about 2 minutes as it slowed to a groundspeed of about 90 knots, which may have been indicative of airwork leading to slow flight or stall maneuvers. The airplane then entered a steep bank and impacted the ground in a nose-low attitude. Both engines and propellers displayed evidence of operation at the time of impact, and postaccident examination revealed no mechanical anomalies that would have precluded normal operation of the airframe or engines. The instructor had a history of obstructive sleep apnea. The investigation was unable to determine how well the condition was controlled, if he had symptoms from the condition, or if it contributed to the accident. Toxicology testing revealed low levels of ethanol in specimens from both pilots; however, it is likely that some or all of the ethanol detected was a result of postmortem production, and it is unlikely that alcohol impairment contributed to the accident. Toxicology testing also detected the primary psychoactive compound of marijuana, tetrahydrocannabinol (THC), and its metabolite, tetrahydrocannabinol carboxylic acid (THCCOOH), in specimens obtained from comingled remains; the investigation was unable to reliably determine which pilot had used the impairing illicit drug. Additionally, it is not possible to determine impairment from tissue specimens; therefore, the investigation was unable to determine whether THC impaired either of the pilots or if it may have contributed to the accident.

The crew was completing a local night training exercice at Langebaanweg AFB. While completing various manoeuvres, the airplane went out of control and crashed in an open field located near airbase, coming to rest upside down. The aircraft was destroyed and both pilots were injured.

The crew departed Kuala Lumpur-Subang-Sultan Abdul Aziz Shah Airport at 0835LT on a local training flight. Ten minutes later, the left engine caught fire and failed, forcing the captain to attempt an emergency landing. The aircraft crash landed in the sea, few metres off the beaches of Taman Malawati Utama, south of Kuala Selangor. The copilot was injured (broken arm) while seven other occupants escaped unhurt. The aircraft was destroyed by a post crash fire.

On 29 January 2016, at 08:10 a Cessna 425 Conquest, which was privately operated, crashed approx. 300 meters NNE of threshold Runway 26. 1.1.2 According to the flight plan filled on the 28th January 2016, the flight was scheduled for a renewal of CPL and IR ratings for the two pilots by a Designated Examiner (DE). Departure time was scheduled at 07:45 at a cruising altitude of FL100 for Hosea Kutako Airport. The pilots requested a procedure for an Instrument Landing System (ILS) approach. The Air Traffic Controller (ATC) cleared them for the procedure for runway 26 ILS approach with QNH 1024. They were also asked to report when at nine miles-inbound. At around nine miles they reported their location and were instructed to continue the approach along the glide slope. The DE requested a VOR approach for their next approach and an early right hand turnout that was approved by ATC who also required them to report when going around. The ATC stated that he saw them at around 4nm on final approach. He then stated that he looked away for a moment after which he heard a slight bang, then saw a ball of flames at about 300 meters north of threshold runway 26. He called out to the aircraft three times whilst looking out for it when he finally concluded that it could have been V5-MJW that had crashed. The ATC pressed a crash alarm after a moment when it did not go off, the controller then called the fire station and alerted them of the occurrence. The Airport’s Fire and Rescue team after receiving the initial notification from the ATC took around 10 minutes to reach the site, by that time fire had engulfed the plane and its occupants. The team took 3-4 minutes to extinguish the fire. The weather was reported as fine with winds about 140° at 08 kts with scattered clouds at 4000ft and unrestricted visibility.
